^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) ``fd``
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)     File descriptor returned by open().
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) ``mask``
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29)     Mask with channels to enable tx. Channel 0 is the least significant bit.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) ===========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) Some IR TX devices have multiple output channels, in such case,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) :ref:`LIRC_CAN_SET_TRANSMITTER_MASK <LIRC-CAN-SET-TRANSMITTER-MASK>` is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) returned via :ref:`LIRC_GET_FEATURES` and this ioctl sets what channels will
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) send IR codes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) This ioctl enables the given set of transmitters. The first transmitter is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) encoded by the least significant bit and so on.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) When an invalid bit mask is given, i.e. a bit is set, even though the device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) does not have so many transitters, then this ioctl returns the number of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) available transitters and does nothing otherwise.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) Return Value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) ============
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) On success 0 is returned, on error -1 and the ``errno`` variable is set
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) appropriately. The generic error codes are described at the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) :ref:`Generic Error Codes <gen-errors>` chapter.
